Primary outcomePrimary: First Attempt Success Rate — 59; 65 Participants
Summary
The 90° rotation technique is known to improve the success rate of conventional LMA but its effect in LMA FlexibleTM is not known. We tried to find if 90° rotation technique could increase the first attempt success rate of the insertion of LMA FlexibleTM compared to standard technique.
